Bear with me 
DD is 14 and in year 9. A few of her friends are "dating" boys, though this doesn't seem to involve going on actual dates - just chatting on SM and referring to each other as my bf or my gf 
But a couple of them are doing "proper courting" as my nan would say. And her Yr 10 friend stays over at her bf's most weekends.
It just seems too much, too young. I want DD to concentrate on her studies and her sport and enjoy friendships with both sexes rather than risk the emotional turmoil of teen romance before GCSEs.
What do you think?
